Automaxx® Face Clamps feature new technology that adjusts the clamps automatically, eliminating the need to readjust the clamp for every change in material thickness. Just squeeze the padded handles and the clamp locks closed, no matter what the thickness.

Automaxx® Face Clamps also feature easy-to-regulate clamping pressure that you can simply set and forget. Auto-Adjust™ technology maintains the desired pressure every time. In addition to these great features, Automaxx® Face Clamps feature extra-large clamp faces, comfortable padded handles, and heavy-duty construction. Available in two sizes, both are compatible with the Kreg Jig®, Kreg Portable Base, and Kreg Jig® R3.
